QUESTION 41The implementations group has been using the test bed to do a `proof-of-concept’ that requires both Client 1 and Client 2 to access the WEB Server at 209.65.200.241. After several changes to the network addressing, routing scheme, DHCP services, NTP services, and FHRP services, a trouble ticket has been operated indicating that Client 1 cannot ping the 209.65.200.241 address.Use the supported commands to Isolated the cause of this fault and answer the following questions.On which device is the fault condition located?

A. R1B. R2C. R3D. R4E. DSW1F. DSW2G. ASW1H. ASW2

Answer: GExplanation:Since the Clients are getting an APIPA we know that DHCP is not working. However, upon closer examination of the ASW1 configuration we can see that the problem is not with DHCP, but the fact that the trunks on the port channels are only allowing VLANs 1-9, when the clients belong to VLAN 10. VLAN 10 is not traversing the trunk on ASW1, so the problem is with the trunk configuration on ASW1.

QUESTION 42The implementations group has been using the test bed to do a `proof-of-concept’ that requires both Client 1 and Client 2 to access the WEB Server at 209.65.200.241. After several changes to the network addressing, routing scheme, DHCP services, NTP services, and FHRP services, a trouble ticket has been opened indicating that Client 1 cannot ping the 209.65.200.241 address.Use the supported commands to isolated the cause of this fault and answer the following questions.The fault condition is related to which technology?

Answer: BExplanation:Since the Clients are getting an APIPA we know that DHCP is not working. However, upon closer examination of the ASW1 configuration we can see that the problem is not with DHCP, but the fact that the trunks on the port channels are only allowing VLANs 1-9, when the clients belong to VLAN 10. VLAN 10 is not traversing the trunk on ASW1, so the problem is with switch to switch connectivity, specifically the trunk configuration on ASW1.

QUESTION 43The implementations group has been using the test bed to do a `proof-of-concept’ that requires both Client 1 and Client 2 to access the WEB Server at 209.65.200.241. After several changes to the network addressing, routing scheme, DHCP services, NTP services, and FHRP services, a trouble ticket has been opened indicating that Client 1 cannot ping the 209.65.200.241 address.Use the supported commands to isolated the cause of this fault and answer the following questions.What is the solution to the fault condition?

Answer: BExplanation:We need to allow VLANs 10 and 200 on the trunks to restore full connectivity. This can be accomplished by issuing the “switchport trunk allowed vlan 10,200” command on the port channels used as trunks in DSW1.

Ticket 2 : ACCESS VLANTopology Overview (Actual Troubleshooting lab design is for below network design)– Client Should have IP 10.2.1.3– EIGRP 100 is running between switch DSW1 & DSW2– OSPF (Process ID 1) is running between R1, R2, R3, R4– Network of OSPF is redistributed in EIGRP– BGP 65001 is configured on R1 with Webserver cloud AS 65002– HSRP is running between DSW1 & DSW2 SwitchesThe company has created the test bed shown in the layer 2 and layer 3 topology exhibits.This network consists of four routers, two layer 3 switches and two layer 2 switches.In the IPv4 layer 3 topology, R1, R2, R3, and R4 are running OSPF with an OSPF process number 1.DSW1, DSW2 and R4 are running EIGRP with an AS of 10. Redistribution is enabled where necessary.R1 is running a BGP AS with a number of 65001. This AS has an eBGP connection to AS 65002 in the ISP’s network. Because the company’s address space is in the private range.R1 is also providing NAT translations between the inside (10.1.0.0/16 & 10.2.0.0/16) networks and outside (209.65.0.0/24) network.ASW1 and ASW2 are layer 2 switches.NTP is enabled on all devices with 209.65.200.226 serving as the master clock source.The client workstations receive their IP address and default gateway via R4’s DHCP server.The default gateway address of 10.2.1.254 is the IP address of HSRP group 10 which is running on DSW1 and DSW2.In the IPv6 layer 3 topology R1, R2, and R3 are running OSPFv3 with an OSPF process number 6.DSW1, DSW2 and R4 are running RIPng process name RIP_ZONE.The two IPv6 routing domains, OSPF 6 and RIPng are connected via GRE tunnel running over the underlying IPv4 OSPF domain. Redistrution is enabled where necessary.Recently the implementation group has been using the test bed to do a `proof-of-concept’ on several implementations. This involved changing the configuration on one or more of the devices. You will be presented with a series of trouble tickets related to issues introduced during these configurations.Note: Although trouble tickets have many similar fault indications, each ticket has its own issue and solution.Each ticket has 3 sub questions that need to be answered & topology remains same.Question-1 Fault is found on which device,Question-2 Fault condition is related to,Question-3 What exact problem is seen & what needs to be done for solutionClient is unable to ping IP 209.65.200.241Solution:Steps need to follow as below:– When we check on client 1 & Client 2 desktop we are not receiving DHCP address from R4 Ipconfig — — Client will be getting 169.X.X.X.– On ASW1 port Fa1/0/ 1 & Fa1/0/2 access port VLAN 10 was assigned which is using IP address 10.2.1.0/24.Sh run ——- & check for running config of int fa1/0/1 & fa1/0/2 ========================================================================================================Here we are not able to see access Vlan10 configured for Port Fa1/0/1 & Fa1/0/2 Change required: On ASW1, for configuring Access Vlan under interface fa1/0/1 & 1/0/2 we have to enable command switchport access vlan 10
